Description
Technical Field
The utility model relates to a detection device's technical field specifically is a take measurement function to be used for three-dimensional crooked section bar site survey's utensil of examining.
Background
At present, in the aluminum profile processing industry, for the bending of common aluminum profiles, only a bending die needs to be fixed on a workbench in the bending process, and the two-dimensional bending forming of the aluminum profiles can be realized by adjusting the positions of the die in the X-axis and Y-axis directions. For the curved surface of the three-dimensional section, besides the adjustment of the two degrees of freedom, the position of the die in the Z-axis direction needs to be controlled, and sometimes the die is even required to rotate along the Y-axis and the Z-axis, so that the purpose of bending and forming the section can be achieved.
For the two-dimensional bending workpieces produced in batch, a special checking fixture is generally adopted to detect the processing precision of the shape of the workpieces; however, for the shape detection of the spatial three-dimensional bending workpiece, three-coordinate, three-dimensional laser scanners and profiling checking tools are generally adopted for detection, wherein the detection results of the three-coordinate and laser scanners are accurate, and the results can be used for guiding production. However, the three-coordinate device is precise, needs to work in a constant temperature environment, has long detection time, and cannot rapidly acquire a measurement result. Three-dimensional laser scanners can be used for field inspection but their equipment costs are very high. The profiling checking fixture processed according to the three-dimensional digital analogy is usually used for field measurement, but specific parameters of a bent product cannot be obtained, reference information cannot be provided for improvement of a bending process, and the guidance of process production is not facilitated. Therefore, a three-dimensional bending profile field measurement gauge which is suitable for field operation, has a certain measurement function and can provide reference information for bending process improvement is needed.
Disclosure of Invention
An object of the utility model is to provide a take measuring function to be used for examining utensil of three-dimensional crooked section bar, should examine the utensil and can detect whether qualified while of work piece, can also realize crooked section bar critical dimension and measure, provide reference information for crooked technology improvement, be applicable to the witnessed inspections operation.
The technical scheme is as follows:
the utility model provides a take measurement function to be used for examining utensil of three-dimensional crooked section bar, includes testing platform, still includes that slip measurement seat and profile modeling put the thing and press from both sides, slip measurement seat lay on testing platform, be provided with the scale on the slip measurement seat, the top of slip measurement seat is fixed with the cavity dead lever of vertical placing, through the adjustable scale pole of installing an upwards stretching of holding screw in the cavity dead lever, profile modeling put the thing and press from both sides and set up and be used for detecting the profile modeling of waiting to detect the key dimension position of work piece and put the thing seat according to the key dimension position of standard three-dimensional crooked section bar, the bottom that the thing pressed from both sides is fixed with the screw rod in the profile modeling, installs the top at the scale pole through screw rod threaded connection.
Further preferred is: the sliding measuring seat comprises a base, a middle sliding seat and an upper sliding seat, a longitudinal sliding rail and a longitudinal graduated scale are arranged at the top of the base, the bottom of the base is laid on the detection platform, a longitudinal sliding groove matched with the longitudinal sliding rail of the base is arranged at the bottom of the middle sliding seat, the middle sliding seat is installed at the top of the base through the longitudinal sliding groove and the longitudinal sliding rail in a matching mode, a transverse sliding rail and a transverse graduated scale are arranged at the top of the middle sliding seat, a transverse sliding groove matched with the transverse sliding rail of the middle sliding seat is arranged at the bottom of the upper sliding seat, and the upper sliding seat is installed at the top of the middle sliding seat through the transverse sliding groove and the transverse sliding rail in a matching mode.

Further preferred is: the transverse sliding rail is a dovetail guide rail, and the transverse sliding groove is a dovetail groove.
Further preferred is: the bottom of the base is connected with the detection platform in a sticking mode. Preferably: the sticking connection is magnetic sticking connection.
For three-dimensional curved surfaces it is difficult to control the entire curve completely, especially for longer curved profiles. The profile of the three-dimensional bent profile is a space spline curve, so that the profile can not be detected by controlling the profile of the profile like a two-dimensional bent profile; in order to ensure the bending precision of the section bar, the detection is considered to be carried out in a mode of replacing a line by a point. Therefore, when the gauge with the measuring function for the three-dimensional bent section is used, the key detection points are firstly determined according to the profile of the standard three-dimensional bent section and the assembly requirement, the relative coordinates of the key points are obtained, the projection positions of the detection points on the horizontal plane are determined through the coordinates, and the number of the required struts is determined through the number of the projection positions. Selecting a proper pillar contact position according to the section of the profile, determining the shape of the profiling object placing clamp, determining the positions of the sliding measuring seat and the scale rod by using a standard three-dimensional bent profile, placing a workpiece to be detected on the profiling object placing clamp, and measuring the shape of the bent profile by observing the contact condition of the profiling object placing clamp above the scale rod and the workpiece to be detected. If the contact condition is poor, the difference of the height of the scale rod and the theoretical shape is determined by adjusting the lifting of the scale rod, and if the contact condition is poor in the horizontal direction, the position of the middle sliding seat and the position of the upper sliding seat are adjusted to determine the size of the change. And (4) integrating the measurement results of all positions, guiding the bending process until the drawing requirements are met, and detecting the production sample after the original coordinates are kept unchanged after the drawing requirements are met.
Generally speaking, this take measuring function to be used for examining utensil of three-dimensional crooked section bar can detect whether qualified the work piece, can also realize crooked section bar key dimension and measure, improves for crooked technology and provides reference information, is applicable to the witnessed inspections operation, and the commonality is high and is not limited to the radian, and the thing clamp is put in order to adapt to different cross-section bars in the accessible change profile modeling, and adaptability is good, repeatedly usable, and is with low costs.
